JOHN W. FISHER, OF NEW YORK, ASSIGNOR OF ONE-HALF TO MICHAEL HAMMA, OF BROOKLYN ,N. Y.

CULINARY VESSEL.

SPECIFICATION forming part of Letters Patent No. 254,97, dated March 14, 1882.

, Application filed January 14, 1882. (No model.)

To all whom it may concm'n Beit known that I, JOHN WVFISHER, a citizen of the United States, residingat New York, in the county of New York and State of New York, haveiuveuted certain new and useful Improvements in Culinary Vessels; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- 1o pertains to make and use the same, reference being had to the accompanying drawings, ttnd to the letters and figures of reference marked thereon,which form a part of this specification.

My invention relates to that class ofculinary 1 vessels in which an inner vessel of earthenware or other suitable material is inclosed in an outer metallic casing, band, or ring, so as to form a space or chamber for the access of heat around and in contact with the walls of said inner vessel.

The object of the invention is to provide a simple means of securely attaching the inner vessel to its inclosiug casing, band, or ring; and the invention consists in certain novel 2 features of construction, as hereinat'termore fully described and claimed.

1n the annexed drawings, which fully illustrate my invention, Figure l is a vertical section of a culinary vessel embodying my im- 0 provements. Fig. 2 is an exterior view of the same, showing the complete vessel provided with a bail. Figs. 3 and 4 are bottom views of the outercasing, showingperforationstherein; and Fig. 5 is an enlarged sectional detail,

illustrating the manner ofcoilnecting the inner vessel with its inclosiug casing or band.

Like letters of reference indicate like parts.

The inner vessel or how], A, may be made of earthenware or other suitable material, and

in any desired form, butis preferably tapered from above downward, as shown in Fig. 1. On the outer surface of this vessel or bowl, near or toward its upper part, is formed an annular shoulder, a, beyond which the outer surface of 5 the bowl is continued vertically upward to an annular groove, a, the upper part or side of which groove is of greater depth than thelower part and forms a slightly-curved shoulder, a Above this upper shoulder, a the outer surface of the bowl is again continued in a vertical line to the rim of the bowl. It will be observed that the circumference of the bowl above the shoulder a is greater than it is between the groove and lower shoulder, a, thus forming a nearly even and continuous vertical surface on the. outer side of the vessel when the inclosiug band is in position, as shown by dotted line in Fig. 5.

The band B or wall of the outer inclosiug casingis bent or turned inward at its upper edge, b, to engage within the annular groove a of the inner vessel or bowl. This band is fitted closely against the outer side of the bow], above theshoulder a, and by means of the engagement of the projection or inwardly-bent, edge 1) within the groove (1/ is held sccurelyin contact with said bowl. It will be seen thata space is left within the casing 13, between its vertical' walls and the inclined sides of the bowlA, for the circulation of heat in contact with said bowl. The lower edge of the band B is curved inwardly and upwardly to form an annular groove or recess, 1), for the reception ofa corresponding flange on the bottom B. This bottom is preferably perforated for the morercady passage of heat to the space or chamber surrounding the bowl. The form of these perforations b may be circular. as shown in Fig. 4, or maybe elongated and disposed near the edge of the bottom, as shown in Fig. 3. 8o

\Vhen the inner vessel or bowl is inclosed in acasing having a perforated bottom it will be seen that a more ready access is afforded for the introduction or generation of heator steam in the space surrounding said inner vessel than is possible with a bottom not perforated. By this means the contents of said inner vessel may also be thoroughly heated without exposure to the direct action of the fire. Ifdesired, however, the bottom may be entirely 9o dispensed with and the bowl inclosed in the V band B alone. Y

The utensil may be provided with abail, O, which is attached by means oflugs c, formed on or secured to the inclosiug band or casing. 5 I will be seen that when the parts of the utensil are connected the bowl A is held or locked securely inpos-ition, the engagement of the inwardly-turned flange or edge I) within the groove a and the pressure of said hand against that portion of the bowl above the shoulderabeing such that the bowl is prevented from being moved up or down within the inelosing-band.

Having thus described my invention, whatI claim as new, and desire to secureby Letters Patent, is-

1. Theeombiuation, with the bowl A, having annular shoulders at a and groove to, the circumference of the upper shoulder being greater than that of the lower one, of the band B, having an inwardly-bent upper edge, 1), adapted to engage within the groove a,whereby said parts are securely connected, substantially as described.

vided near the top with annular shoulders and 20 groove, and the casing B, having vertical walls and an inwardly-turned edge, 1), adapted to engage with the annular groove formed in the bowl, said casing being provided with a bail, O, and having at its lower end an annular recess, b, for the attachment of the perforated flanged bottom B, a space being left between the bowl and its casing for the circulation of heat, substantially as specified. v

In testimony whereofI affix my signature in 0 presence of two witnesses.

JOHN W. FISHER.
